* Remove more dead code from minzip.Narayan Kamath2015-02-271-1/+1
| | | | | | | | | | | | I've added explanatory comments to mzExtractRecursive because that function will live on as a utility even after we move the zip format related logic to libziparchive. bug: 19472796 (cherry-picked from commit c9ccdfd7a42de08c47ab771b94dc5b9d1f957b95) Change-Id: I8b7fb6fa3eafb2e7ac080ef7a7eceb691b252d8a

* unconditionally apply SELinux labels to symlinksNick Kralevich2014-10-231-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | At the end of the OTA script, we walk through /system, updating all the permissions on the filesystem, including the UID, GID, standard UNIX permissions, capabilities, and SELinux labels. In the case of a symbolic link, however, we want to skip most of those operations. The UID, GID, UNIX permissions, and capabilities don't meaningfully apply to symbolic links. However, that's not true with SELinux labels. The SELinux label on a symbolic link is important. We need to make sure the label on the symbolic link is always updated, even if none of the other attributes are updated. This change unconditionally updates the SELinux label on the symbolic link itself. lsetfilecon() is used, so that the link itself is updated, not what it's pointing to. In addition, drop the ENOTSUP special case. SELinux has been a requirement since Android 4.4. Running without filesystem extended attributes is no longer supported, and we shouldn't even try to handle non-SELinux updates anymore. (Note: this could be problematic if these scripts are ever used to produce OTA images for 4.2 devices) Bug: 18079773 Change-Id: I87f99a1c88fe02bb2914f1884cac23ce1b385f91

* Auto create parent directories for rename supportMichael Runge2014-07-211-3/+5

* disable async reboot during package installationDoug Zongker2014-05-231-0/+11
| | | | | | | | | | The default recovery UI will reboot the device when the power key is pressed 7 times in a row, regardless of what recovery is doing. Disable this feature during package installation, to minimize the chance of corrupting the device due to a mid-install reboot. (Debug packages can explicitly request that the feature be reenabled.)

| * add the functions for multi-stage packages to updaterDoug Zongker2013-11-261-1/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to support multi-stage recovery packages, we add the set_stage() and get_stage() functions, which store a short string somewhere it can be accessed across invocations of recovery. We also add reboot_now() which updater can invoke to immediately reboot the device, without doing normal recovery cleanup. (It can also choose whether to boot off the boot or recovery partition.) If the stage string is of the form "#/#", recovery's UI will be augmented with a simple indicator of what stage you're in, so it doesn't look like a reboot loop.

* updater: introduce and set_metadata and set_metadata_recursiveNick Kralevich2013-09-101-0/+274
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce two new updater functions: * set_metadata * set_metadata_recursive Long term, these functions are intended to be more flexible replacements for the following methods: * set_perm * set_perm_recursive Usage: set_metadata("filename", "key1", "value1", "key2", "value2", ...) set_metadata_recursive("dirname", "key1", "value1", "key2", "value2", ...) Description: set_metadata() and set_metadata_recursive() set the attributes on a file/directory according to the key/value pairs provided. Today, the following keys are supported: * uid * gid * mode (set_perm_extd only) * fmode (set_perm_extd_recursive only) * dmode (set_perm_extd_recursive only) * selabel * capabilities Unknown keys are logged as warnings, but are not fatal errors. Examples: * set_metadata("/system/bin/netcfg", "selabel", "u:object_r:system_file:s0"); This sets the SELinux label of /system/bin/netcfg to u:object_r:system_file:s0. No other changes occur. * set_metadata("/system/bin/netcfg", "uid", 0, "gid", 3003, "mode", 02750, "selabel", "u:object_r:system_file:s0", "capabilities", 0x0); This sets /system/bin/netcfg to uid=0, gid=3003, mode=02750, selinux label=u:object_r:system_file:s0, and clears the capabilities associated with the file. * set_metadata_recursive("/system", "uid", 0, "gid", 0, "fmode", 0644, "dmode", 0755, "selabel", "u:object_r:system_file:s0", "capabilities", 0x0); All files and directories under /system are set to uid=0, gid=0, and selinux label=u:object_r:system_file:s0. Directories are set to mode=0755. Files are set to mode=0644 and all capabilities are cleared. Bug: 10183961 Bug: 10186213 Bug: 8985290 Change-Id: Ifdcf186a7ed45265511dc493c4036e1ac5e3d0af

* Update OTA installer to understand SELinux filesystem labelsNick Kralevich2013-07-181-5/+24
| | | | | | | | | | | | | | | | | | Modify the OTA installer to understand SELinux filesystem labels. We do this by introducing new set_perm2 / set_perm2_recursive calls, which understand SELinux filesystem labels. These filesystem labels are applied at the same time that we apply the UID / GID / permission changes. For compatibility, we preserve the behavior of the existing set_perm / set_perm_recursive calls. If the destination kernel doesn't support security labels, don't fail. SELinux isn't enabled on all kernels. Bug: 8985290 Change-Id: I99800499f01784199e4918a82e3e2db1089cf25b

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The bonus data option lets you give an additional blob of uncompressed data to be used when constructing a patch for chunk #1 of an image. The same blob must be available at patch time, and can be passed to the command-line applypatch tool (this feature is not accessible from edify scripts). This will be used to reduce the size of recovery-from-boot patches by storing parts of the recovery ramdisk (the UI images) on the system partition.
